</div>
<p>Welcome to the <em><a class="el" href="class_l_c_d.html">LCD</a> Library</em> for <b>Arduino</b> and <b>Chipkit</b>. It is a derivate of the original <a class="el" href="class_liquid_crystal.html">LiquidCrystal</a> Library as sourced in the Arduino SDK. It has been developed to be compatible with the current <a class="el" href="class_liquid_crystal.html">LiquidCrystal</a> library, its performance is almost 5 times faster and fully extendable if need be.</p>
<p>It supports most <code>Hitachi HD44780</code> based LCDs, or compatible, connected to any project using: 4, 8 wire parallel interface, I2C IO port expander (native I2C and bit bang) and Shift Regiter.</p>
<p>It currently supports 4 types of connections:</p>
<ul>
<li>4 bit parallel <a class="el" href="class_l_c_d.html">LCD</a> interface</li>
<li>8 bit parallel <a class="el" href="class_l_c_d.html">LCD</a> interface</li>
<li>I2C IO bus expansion board with the PCF8574* I2C IO expander ASIC such as <a href="http://www.electrofunltd.com/2011/10/i2c-lcd-extra-io.html" title="I2C LCD extra IO">I2C LCD extra IO</a>.</li>
<li>ShiftRegister adaptor board as described <a href="http://code.google.com/p/arduinoshiftreglcd/" title="Shift Register project home">Shift Register project home</a> or in the HW configuration described below, 2 and 3 wire configurations supported.</li>
<li>ShiftRegister 3 wire latch adaptor board as described <a href="http://www.arduino.cc/playground/Code/LCD3wires" title="ShiftRegister 3 Wire Home">ShiftRegister 3 Wire Home</a></li>
<li>Support for 1 wire shift register <a href="http://www.romanblack.com/shift1.htm" title="ShiftRegister 1 Wire">ShiftRegister 1 Wire</a></li>
<li>I2C bus expansion using general purpose IO lines.</li>
</ul>
